I would think then that I have an IDE slave, so I should use 3-4?

If they're both WD branded, one of them would be "Master with Slave"
and the other one would be "Slave". That's when the two drives
are present on the cable.

If initially you had one WD drive, it would have been "Master only".
As it was by itself on the end of the cable. In other words, you have
to change the jumper setting on the first (existing) drive. It
needs to be changed from "Master Only" (no jumpers) to "Master with
Slave".

Let's try this. The WD800BB-75 IDE drive is in the middle of the
cable. At the other end is the tray with the new WD2500JB drive in it.
The jumper on the former is set to select. Which placement is the
master and the other the slave? Where do the jumpers go on each HD?


If one drive is jumpered Cable Select, the logical thing to do
is set the other one to Cable Select. That takes less brain power :-)

So this might work even though I have 40 wire (grey) cables? 80 are blue?
I thought I'd try it, and it did nothing.
Use an 80 wire cable, which both supports Cable Select, and supports
the higher UDMA modes. You really shouldn't even keep any 40 wire
cables in the house. The 80 wire cables can be used for everything.
They present a better electrical environment for the signals.

If I have to go to 80, I have a problem. The tray that holds the drive
look like it uses 40. If I can't find a way to change that, then I might
need a tray that does. The probably went out of style years ago.

If you want to do Master/Slave stuff, and dispense with Cable Select,
then again, both drives will have to be jumpered in a consistent manner.
With two WD drives, one is Master with Slave, the other is Slave.
Just jumper them, and plug them in.
